We never set it, and libdc1394 0.9.5 is obsolete anyway - 1.0 came out
in 2004.

Note that 1.0 doesn't have the do_extra_buffering parameter.

This reverts commit 41b8479d, reversing
changes made to 531471b0.

Reason: breaks the build.

We don't use -Wcast-align ourselves, but the headers trigger warnings
for those users who do, which is not nice.

It increases performance on some devices like Nexus4.
Target Android SDK version increased up to 14.

They're unsequenced if CV_IMIN3 or CV_IMAX3 are invoked more than once
in a single expression.

added IPP optimization of separable 32f filters; fixed IPP version check in DFT; fixed conditions in IPP optimization of norm functions.

begin_x[1] is not the second component of the element, but the element
after the one pointed to begin_x. When begin_x points to the last
element, that line overwrites data past the end of the allocation, which,
during my tests, happened to contain the reference count for the matrix.
Hilarity ensues.

This is fixed upstream in mariusmuja/flann@b615f26, but that fix
would break binary compatibility, so I had to make a different one.

Since the bug isn't quite obvious, here's an explanation. In the const
version of any::cast, if policy is a small_any_policy, its get_value
returns its input argument. So r becomes a pointer to obj, and the
return value is a reference to a local variable, which is invalidated
when the function exits.
